Description

Technical Field

[0001] The invention relates to the technical field of cable stranding equipment, and in particular to a wire tube device for a hollow main shaft of a cabling machine. Background Art

[0002] Wires and cables are wire products used to transmit electromagnetic energy information and realize electromagnetic energy conversion. In order to improve the power safety and electrical protection capabilities of electrical devices, and meet the needs of anti-interference grounding of communications and automation equipment, the three-phase five-wire system is gradually adopted in low-voltage distribution lines. Five-core cables that separate the neutral line and the protective ground line are becoming more and more common. Large-section five-core cables now usually adopt a tile-shaped structural design, that is, the neutral line core is designed as a round core, and the outside is a five-core cable with a tile-shaped main core and a working neutral line. Such a structural design not only makes the cable structure stable, small in geometric size, saves raw materials, reduces the outer diameter of the structure, and reduces the manufacturing cost of the cable, but also makes the product easy to connect and install.

[0003] The cabling machine is the main equipment for producing power cables, plastic cables and rubber sheathed cables in the wire and cable factory. When the existing large-section tile-shaped five-core cable is twisted on the cabling machine, the flat-drawn neutral line will shake severely in the hollow main shaft of the cabling machine, so that the flat-drawn neutral line and the geometric center of the hollow main shaft of the cabling machine cannot basically coincide, resulting in the neutral line's pay-off tension being difficult to control and the angle of entering the die being not horizontal, and the neutral line often jumps out of the cable core after cabling. This will not only fail to achieve the purpose of reducing the cable core diameter and reducing the product manufacturing cost, but will also make the produced products unqualified and increase the manufacturing cost of the cable. Summary of the invention

[0004] The purpose of the present invention is to provide a wire tube device for the hollow main shaft of a cabling machine, which can effectively reduce the shaking of the neutral line of a large-section tile-shaped five-core cable in the hollow main shaft of the cabling machine, so that the neutral line of the flat-drawn cable is basically coincident with the geometric center of the hollow main shaft of the cabling machine, and the pay-off tension of the neutral line of the flat-drawn cable can be easily controlled and the angle of entering the die can be level, which can effectively reduce the quality problem of the neutral line easily jumping out of the cable core after cabling, and reduce the manufacturing cost of the cable.
